Best Practice Paper : Data Modeling

Introduction
A data model is a conceptual representation of the data structures that are required by a database [Mamčenko, J. (n.d.)]. The data structures gives the information about data objects, associations between data objects, and the rules which administer actions on the objects. A data model serves as a bridge between the concepts of the real world and how the data is physically organized in the actual database. Data modelling has been ongoing for many years but still businesses struggle to extract the value from their data and thus, create well designed, intuitive models [Data Modeling Best Practices. (n.d.).]. With businesses considering for innovative ways to utilize data to gain economical advantage, designing database is now more imperative than ever. When designing a data model, it is imperative to follow best practices to help business make the data driven decisions with confidence. Best practices helps us create data models more confidently.
“Applications come and go, but data is forever,” quoted Justin Cave, lead database consultant at Distributed Database Consulting, noting that programmers usually design databases to cater current needs only without considering the future data expansion. Taking shortcuts in present will make it difficult to add new functionality in future. Michael Blaha, a partner at Modelsoft Consulting and author of seven books including "Object-Oriented Modeling…

organisation rather than opting for an ‘off the shelf’ closed option such as ‘Best Practise’ or high performance work practices. Theorists have yet to settle on a definitive model for best practise, which itself suggests a certain degree of flexibility is built into the interpretation of what it could be. Here lies the first contradiction to the pro best practise argument as these rigid principals are yet to be defined. Debatably, best practise principals should be enforceable regardless of the organisational…
